The MapReduce-MPI (MR-MPI) library is open-source software that implements the
MapReduce operation popularized by Google on top of standard MPI message
passing.

The MR-MPI library is written in C++ and is callable from hi-level langauges
such as C++, C, Fortran. A Python wrapper is also included, so MapReduce
programs can be written in Python, including map() and reduce() user callback
methods. A hi-level scripting interface to the MR-MPI library, called OINK, is
also included which can be used to develop and chain MapReduce algorithms
together in scripts with commands that simplify data management tasks. OINK has
its own manual and doc pages.

This package contains the libraries needed to run MapReduce-MPI applications.
